A Tragic Compromise on Stem Cell Derivation

A tragic compromise on stem cell derivation

It appears that the official policy of the US government for federally funded studies of human embryo stem (ES) cell researchwill exclude the derivation of ES cells (National Institute of HealthGuidelines for ResearchUsingHumanPluripotent StemCells, 65 FR 69951 (November 21, 2000)). In taking this decision, theNational Institutes of Health (NIH) is not to be blamed, nor should wewring our hands...

Derivation of embryonic stem cell lines.

Derivation of human embryonic stem cell lines.

Human embryonic stem cells (hESC) are undifferentiated cells derived from an early embryo that can grow in vitro indefinitely, while retaining their capability to differentiate into specialized somatic cell types. Over the last decade there has been great interest in derivation and culture of these cells, as they can potentially provide a supply of readily available differentiated cells and tis...

Microglia as a stem cell

Microglia is considered the only cell population of mesodermal origin, which comprises 10% of the cells in brain parenchyma. Recent neural stem cell (NSC) studies demonstrate that the brain has regenerative potential. NSCs do not give rise to microglial cells, however indicating that NSCs alone cannot complete the regenetion of the brain. Although the role of microglia is not fully understood, ...
